Call

What it does

When your agent uses it

• You want to phone Claude
• Start a voice conversation
• Dial in for a project brainstorm
• Get a verbal status update

Example prompts

• “/call”

Requirements

• Python 3
• Node.js
• Pre-approved tools (allowed-tools): Bash, Read, Write, AskUserQuestion

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1Setup stores your Vapi API key and creates voice tools
2. 2Register snapshots your project context (git status, recent files, etc.)
3. 3Start runs a local server + tunnel so Vapi can reach your code
4. 4Calls use Opus 4.5 with your project context preloaded

What it can do on your machine

Read from SKILL.md and the folder at commit bfc0ea2. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash
  • Read
  • Write
  • AskUserQuestion

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships script files (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • pip
  • npx

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • xxx.loca.lt

  Also links to:

  • dashboard.vapi.ai

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Call loads about 759 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 274 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~56

When it runs · the whole SKILL.md, loaded when a task matches

~759

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

• NotePre-approves every shell command (allowed-tools: Bash)SKILL.md

  allowed-tools: Bash, Read, Write, AskUserQuestion

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
